How to prevent bacterial wilt seedling death in strawberries? These measures you need to master

During strawberry cultivation, the phenomenon of bacterial wilt seedling death can occur, which greatly affects yield and returns, bringing huge economic losses to farmers. So what causes bacterial wilt seedling death in strawberries? Let's take a look at the detailed introduction.

I. Causes

The main cause of bacterial wilt seedling death in strawberries is a sudden drop in temperature; sustained low temperatures lead to the reproduction and infection of Rhizopus and gray mold, thereby worsening the bacterial wilt seedling death phenomenon. In addition to the drop in temperature, it is also related to variety, soil moisture content, fertilizer type, and cultivation management.

II. Preventive measures

1. Select good varieties

Strawberries have strong adaptability, but a sudden drop in temperature makes it difficult for their root system to absorb water, hindering water transport, and their cold resistance is relatively weak. Many growers mostly choose early-maturing varieties, whose cold resistance and stress resistance are weaker than those of open-field cultivation, so the mortality rate is high; therefore, good varieties must be selected when planting.

2. Apply more organic fertilizer

When applying base fertilizer, increase the content of organic fertilizer, especially paying attention to the content of phosphorus and potassium fertilizer, and pay attention to the application rate of nitrogen fertilizer, so as to avoid the seedlings absorbing too much nitrogen, causing the leaves to be dark green and the aboveground part to grow too late, making them highly prone to bacterial wilt seedling death when encountering low temperatures; it will also delay flower bud differentiation and fruiting, affecting yield.

3. Watch out for low temperatures

Always pay attention to weather changes, and take preventive measures in advance before low temperatures and cold arrive. Flat covering can be used, with straw curtains added at night, and the film and curtains removed promptly when the weather clears or the temperature rises, which can avoid bacterial wilt seedling death.

4. Replant in time

When planting, reserve some insurance seedlings for use against pests, diseases, or man-made damage. When plants are damaged or die, promptly pull out the diseased and dead seedlings, clear away the root zone soil, and fill in soil and replant in time.

5. Spray for prevention and control

Once seedlings are injured, immediately spray pesticides and growth regulators to help the plants recover as quickly as possible and enhance disease resistance, so as to avoid infection by pathogens.
